Information Theory – The Big Idea 
 
A
In April 2002 an event took place which demonstrated one of the many applications of information theory. 
The space probe, Voyager I, launched in 1977, had sent back spectacular images of Jupiter and Saturn and 
then soared out of the Solar System on a one-way mission to the stars. After 25 years of exposure to the 
freezing temperatures of deep space, the probe was beginning to show its age. Sensors and circuits were on 
the brink of failing and NASA experts realised that they had to do something or lose contact with their probe 
forever. The solution was to get a message to Voyager I to instruct it to use spares to change the failing parts. 
With the probe 12 billion kilometres from Earth, this was not an easy task. By means of a radio dish 
belonging to NASA’s Deep Space Network, the message was sent out into the depths of space. Even 
travelling at the speed of light, it took over 11 hours to reach its target, far beyond the orbit of Pluto. Yet, 
incredibly, the little probe managed to hear the faint call from its home planet, and successfully made the 
switchover. 
B
It was the longest-distance repair job in history, and a triumph for the NASA engineers. But it also 
highlighted the astonishing power of the techniques developed by American communications engineer 
Claude Shannon, who had died just a year earlier. Born in 1916 in Petoskey, Michigan, Shannon showed an 
early talent for maths and for building gadgets, and made breakthroughs in the foundations of computer 
technology when still a student. While at Bell Laboratories, Shannon developed information theory, but 
shunned the resulting acclaim. In the 1940s, he single-handedly created an entire science of communication 
which has since inveigled its way into a host of applications, from DVDs to satellite communications to bar 
codes – any area, in short, where data has to be conveyed rapidly yet accurately. 
C
This all seems light years away from the down-to-earth uses Shannon originally had for his work, which 
began when he was a 22-year-old graduate engineering student at the prestigious Massachusetts Institute of 
Technology in 1939. He set out with an apparently simple aim: to pin down the precise meaning of the 
concept of ‘information’. The most basic form of information, Shannon argued, is whether something is true
